Backend and data engineering for e-commerce and SaaS

I build the pipelines, APIs and integrations that have to be correct — Shopify apps, data warehouses, and AI features inside existing PHP codebases. Eleven years, most of it spent inside systems I didn’t write.

What I do

01

Shopify apps and e-commerce integrations

Embedded apps, OAuth and app lifecycle, GraphQL Admin API, and getting store data somewhere it can actually be reported on.

02

AI features in existing PHP applications

An LLM feature in production since 2023 — not a prototype. Prompts that stay stable, failures that degrade gracefully, output a user can trust.

03

Data pipelines and warehouse ETL

Multi-tenant sync that survives being re-run: idempotent writes, watermarks, leases, no duplicates and no silent drift.

Who you’re hiring

I’m the person who gets handed a backend nobody else wants to touch — and makes it behave.

Nine years at Qualia as the backend and API specialist: a no-code predictive analytics SaaS where I owned both the PHP API and the Python model service, a royalty and settlement platform built from scratch, and outsourced work for a national broadcaster and a university.

Currently taking work

Available for roughly 20 hours a month, working async. I reply within 24 hours.

Best fit: a maintenance retainer, or a scoped project with a deadline.

Tell me what’s breaking, or what needs building.

A paragraph is enough to start. If it isn’t a fit I’ll say so quickly rather than waste your week.
